Forward Looking Statements

Certain statements made herein are not historical facts but are forward-looking statements for purposes of the safe harbor provisions under The Private Securities Litigation Reform Act of 1995. Forward-looking statements generally are accompanied by words such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “should,” “would,” “plan,” “predict,” “potential,” “seem,” “seek,” “future,” “outlook” and similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding future events, the Business Combination, the estimated or anticipated future results and benefits of the combined company following the

Business Combination, including the likelihood and ability of the parties to successfully consummate the Business Combination, future opportunities for the combined company, and other statements that are not historical facts. These statements are based on the current expectations of ARYA’s management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on, by any investor as a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of Arya and Immatics. These statements are subject to a number of risks and uncertainties regarding ARYA’s businesses and the Business Combination, and actual results may differ materially. These risks and uncertainties include, but are not limited to, general economic, political and business conditions; applicable taxes, inflation, interest rates and the regulatory environment; the outcome of judicial proceedings to which Immatics is or may become a party; the inability of the parties to consummate the Business Combination or the occurrence of any event, change or other circumstances that could give rise to the termination of the Business Combination Agreement; the outcome of any legal proceedings that may be instituted against the parties following the announcement of the Business Combination; the receipt of an unsolicited offer from another party for an alternative business transaction that could interfere with the Business Combination; the risk that the approval of the shareholders of ARYA or Immatics for the potential transaction is not obtained; failure to realize the anticipated benefits of the Business Combination, including as a result of a delay in consummating the potential transaction or difficulty in integrating the businesses of ARYA and Immatics; the risk that the Business Combination disrupts current plans and operations as a result of the announcement and consummation of the Business Combination; the ability of the combined company to grow and manage growth profitably and retain its key employees; the amount of redemption requests made by ARYA’s shareholders; the inability to obtain or maintain the listing of the post-acquisition company’s securities on Nasdaq following the Business Combination; costs related to the Business Combination; and those factors discussed in ARYA’s Annual Report on Form 10-K for the year ended December 31, 2019, which was filed with the SEC on March 6, 2020 under the heading “Risk Factors,” as updated from time to time by ARYA’s Quarterly Reports on Form 10-Q and other documents of ARYA on file with the SEC or in the proxy statement that will be filed, or to be filed, with the SEC by ARYA. There may be additional risks that ARYA presently does not know or that ARYA currently believes are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements provide ARYA’s expectations, plans or forecasts of future events and views as of the date of this communication. ARYA anticipates that subsequent events and developments will cause ARYA’s assessments to change. However, while ARYA may elect to update these forward-looking statements at some point in the future, ARYA specifically disclaims any obligation to do so. These forward-looking statements should not be relied upon as representing ARYA’s assessments as of any date subsequent to the date of this communication. Accordingly, undue reliance should not be placed upon the forward-looking statements.
